Type 1 diab with prolif diab rtnop without mclr edema, l eye

This code signifies a patient diagnosed with Type 1 diabetes who has developed proliferative diabetic retinopathy (PDR) in their left eye. PDR is an advanced stage of diabetic retinopathy characterized by the growth of new, abnormal blood vessels on the retina, which can lead to severe vision loss. Importantly, this specific code indicates the absence of macular edema in the affected eye.

Use this code when documentation clearly states Type 1 diabetes and confirms proliferative diabetic retinopathy affecting the left eye, with explicit notation that macular edema is not present. This diagnosis is typically made by an ophthalmologist following a dilated eye exam, fundoscopy, or imaging studies like fluorescein angiography.

• Always verify the type of diabetes (Type 1 vs. Type 2) and the specific eye affected (left, right, or bilateral).
• Confirm the presence or absence of macular edema, as this significantly alters the code selection.
• Sequence this code after the primary diabetes code (E10.-) if the retinopathy is a manifestation.
